StreamStats in Idaho
Six reports document the regression equations available in StreamStats for Idaho, the errors associated with the estimates, and the methods used to develop the equations and to measure the basin characteristics used in the equations. The last report by Rea and Skinner (2009) includes full metadata descriptions and links to download the geospatial data sets used by StreamStats for Idaho. Users should familiarize themselves with these reports before using StreamStats to obtain estimates of streamflow statistics for ungaged sites.

NOTE: Idaho StreamStats can be used to obtain estimates of flow statistics from regression equations for portions of northwestern Utah and northeastern Nevada that drain northward to the Snake River in Idaho. The Idaho regression equations are considered more applicable in this area than the Utah equations. Estimates of flow statistics from the Utah regression equations are not available for this area using the Utah StreamStats application, and StreamStats is not implemented for Nevada. In the Idaho user interface, when the map is zoomed into scales of at least 1:4 million, the areas of Utah and Nevada where estimates of flow statistics can be obtained are not hatched. Hatching appears along all other border areas in those states to indicate that the Idaho regression equations are not applicable there.
